"The parties need to expedite things and resolve this unfortunate series of events."

The court heard Sitters' case might be considered for the Mental Health Court.

Judge Everson ordered a pre-sentence report, together with the October 30 psychiatrist's report, be released to the defence and prosecution immediately.

He also ordered the psychiatrist's report be released to the prison mental health service.

And the judge ordered that a further formal intellectual, capacity and "adaptive functional" assessment be obtained.

"I have no idea as to how long it takes for that type of report to be prepared, but it should be prepared as soon as possible," Judge Everson added.

"The reason I say I don't know is that, when I originally ordered the report to include a psychiatric assessment, I was told that it takes about a month."

"But I've now got that report and [it] did not contain the level of detail which I'm seeking."

After the jury found Sitters guilty last month, Judge Everson started hearing sentencing submissions but stopped part-heard, as the defence did not have professional medical evidence on intellectual capacity to put before the court.
